CM-400


The CM-400 is a Chinese supersonic anti-ship missile manufactured by China Aerospace [Science and Industry Corporation].

Development and history

The CM-400AKG was unveiled at the 2012 China International Aviation & Aerospace Exhibition, where it was claimed to have entered service on Pakistan Air Force CAC/PAC JF-17 Thunders. At the 2013 Dubai Airshow, a Pakistani military source claimed the missile was in Chinese service, and that an anti-ship version was in development. In 2014, a PAF JF-17 was spotted carrying two – possibly mock-up – CM-400AKGs, suggesting the missile was still in development.
At the 2013 Paris Air Show, Fábrica Argentina de Aviones officials revealed the missile's performance was a major reason for their interest in co-producing the JF-17.

Design

The CM-400AKG supersonic anti-ship missile is an air-launched cruise missile and a derivative of the SY-400 guided rocket, also developed by the China [Aerospace Science and Industry Corporation].
The CM-400AKG is advertised as having a length, a diameter, a mass of, and a range of, and capable of carrying either a blast warhead or a penetrator warhead. It has a high cruise altitude and a steep terminal dive, with a maximum terminal speed of Mach 4.5 to Mach 5. Seeker options include "INS + GNSS + Passive Radar Seeker," potentially for anti-ship with a circular error probable of., and "INS-GNSS+IR/TV Seeker", with a CEP of. Pakistan air force officials described the missile as "an aircraft carrier killer."
In the aftermath of the 2025 India–Pakistan conflict, Pakistan Air Force officials claimed that CM-400AKG has a range of, a terminal locking range of, a speed of Mach 5, and a passive mode for anti-radiation and suppression of enemy air defenses missions.

Operational history

The Pakistan Air Force reportedly purchased 60 CM-400AKG missiles from China in 2017 and 2018.
The CM-400AKG saw its first-ever live combat use during the 2025 India–Pakistan conflict, when the PAF used the missiles to target an Indian S-400 air defense system. Pakistan claims to have struck the 96L6E Cheese Board and 91N6 Big Bird radars; Though the said said claims remain unconfirmed.
